Title: Automatical level adjustment digital recording circuit
Inventor: CHIBA KATSUHIKO
IPC: G11B20/10
Filed: 1992-09-30
Abstract: PURPOSE:To record a sound at a level in linear proportion to an input signal level by writing it once on a digital recording medium at a scale in a maximum level from sequential sound recording start, and revising to the maximum level scale at an ending time after sound recording is ended and writing it again on the digital recording medium. CONSTITUTION:An audio signal from an input terminal 1 is amplified 2 and is subjected to sample-and-hold 4 through an LPF 3, and potential made an absolute value by an absolute value circuit 6 is applied to a signal line 26. The potential is subjected to sample-and-hold 5, the more the potential is lowered the more the signal on the signal line 24 is voltage-amplified 7, and after being A/D converted 8 and quantized, is digital-processed by a PCM signal processing circuit 15 and a RAM 14, and is written on a digital tape 23. Then when the sound recording is ended by a switches group 17, the contents of the RAM 13 and the tape 23 are collated and the contents of the tape 23 is recalculated by the circuit 15 and rewritten on the tape 23 again regarding the maximum level stored in the RAM 13 as the scale. In such a manner a dynamic range is expanded.

Abstract: PROBLEM TO BE SOLVED: To extremely reduce the variance of performance between fixing devices in an electrophotographic device on a front stage and in an electrophotographic device on a back stage by providing the device with a recording material lifting device having a projection member which can be relatively displaced from the surface of a preheater. SOLUTION: The part of the preheater 10 near to a heating roll 11a in the carrying direction of a printing paper 6 is constituted of a high-temperature preheater 10a and the part thereof on an upstream side in the carrying direction of the paper 6 with respect to the preheater 10a is constituted of a lowtemperature preheater 10b. The projection member 15a of the recording material lifting device 15 is arranged so that it can be relatively displaced from the surface of the preheater 10a. When a fixing action is not executed, a pressure roll 11b is separated from the roll 11a and the press-contact state between them is released. Besides, the preheater 10 and suction devices 14 and 17 are almost simultaneously retreated from the carrying path of the paper 6. At this time, the paper 6 on the preheater 10a is pushed up by the projection member 15a of the lifting device 15.

Next, the substrate 11 is scrabbled to be junctioned with a lead frame. At this time, the lowering amount of the collet 10 is computed by the extrusion amount data from the bottom of the collet 10 detected by the detector 17 to be stored in the RAM. Finally, the junction is completed when the substrate 11 abuts against the lead frame at a specific depression amount to be scrabbled.

Title: Electronic music instrument
Inventor: MAEDA TOSHIO
IPC: G10H1/057
Filed: 1990-10-23
Abstract: PURPOSE:To obtain the music sound of a legato play by the sound channel of one channel by providing a transit signal generating means outputting a transit signal for temporarily reducing the level of the music sound signal of a part where a high sound is varied by the legato play. CONSTITUTION:A transit sound generating means TRS generates the transit signal by a signal from an envelope signal generating means ENV and a legato signal LG. The transit signal rises between the depression of a key and a release finish of the envelope signal (2-5) when the output of the sound is eliminated, and the timing of the depression of an E key which detects the legato play is reduced by the level. In this case, the rise and the rising characteristic of a part T reducing the level are set as the characteristic not to be heard as a noise. Thus, when the legato play is performed, the legato play sound is efficiently generated only by the sound channel of the one channel, and a burden to a CPU is reduced.

Title: Method and device for detecting presence of defect in transparent article
Inventor: JIYOUJIFU JIEIMUZU AARU
IPC: B07C5/34
Filed: 1985-12-20
Abstract: An apparatus and method for detecting sidewall and dimensional defects in transparent containers includes a laser scanning system (40, 42, 44) positioned astride a conveyor (12) in a production line. In an upstream inspection zone a laser beam vertically scans a portion of the side wall of the container. Photosensors (62, 64, 66, 68) positioned in a detection chamber (56) detect the specific effect which any defect has upon the laser beam by determining the location of light passing through the container and comparing its intensity against pre-set thresholds. A flaw signal is generated when a threshold is exceeded. The number of flaw signals is counted (78) and when the count equals a pre-set value a reject signal is generated (98) to eject the defective container from the conveyor. If a container is not rejected, is passes through a rotator assembly which rotates the container precisely 90 DEG . The container then continues to a similar downstream inspection zone where an indentical scanning and detection process is repeated with regard to the previously uninspected portions of the side wall of the container.
